To, all whom it may co'rwem: Y

Be it known that I, SAMUEL EVANS, a subject of the King of Great Britain, and a resident of Chicago, in the county of Cook and 'State of-Illinois,'have invented certain new and useful Improvements in. Washing-Machines for Glass, of which the following, when taken in connection with the drawin s acwith but little breakage thereto.

companying and formin a part hereo is a full and com lete speci catlon sufficient to enable those s 'lled 1n the art to which it pertains to understand, make, and use the same.

This invention relates to a machine for the washing of sheet glass and the object of the invention is to obtain a machine bymeans of which sheets of lass requirin the use of lye or other fluids injurious to t e skinof a person may be washed and cleaned without requiring the operator or operators-to come in-contact with such lye or otherli uid or to handle such glass while the lye or ot er liquid is thereon. 7

A further object of the invention is to obtain means wherebyhheets of glass of varyin size and thickness may be thoroughly washed A further object of the invention is to obtain a machinewhereby the washing of sheets of glass .is continuous; and amachine which may be economically o eratedby two ersons, one to place the s sets of glass w 'ch are to be washed in or .on the machine, and

one to take the washed sheets of glass from the machine.

In the dra 'in s referred to Figure 1 is an elevation of a washing machine embodying this invention, with portions of the side of" the frame thereof broken away to expose. operative'parts of the machine to view. Fig.

A reference letter applied to. designate a given part is used to indicate such part throug out the several [figures of the drawings wherever the same appears.

A is the frame of the machine, and B is an apron com rising flexible belts b,- b, and slats b, b. C, igs. 1, 2 and 7, is a shaft rotatably mounted on frame Aand C Figs. 1, 2 and 5 is a shaft similar to shaft C which is also r0- tatably mounted onv frame A. D, D are, respectively, wheels on shafts O and O Flexible belts b, b, of apron B extend over the wheels D, D respectively, and such apron is actuated by the rotation of the shaft C, the wheels 1) beingrigidly secured to such shaft. 8/

E is an inclined table supported by the frame A, see Figs. 1 and 6. It will be observed that the lower end of inclined table E is not adjacent to the shaft C butis placed at r such a distance therefrom that whena sheet of lass to be washed. is placed on the a ron B t e lower end of such sheet of glass wi lbe moved by the apron to over the collecting panF by the time the upper end or edge of such sheet of glass is over such inclined table. When the upper end or edgeof a sheet of glass on the apron B is. over the inclined table E liquid is directed onto such sheet of glass by or from such inclined table, the

on or near to such inclined apron resting table so that i uid delivered from receptacle G on to the a ron flows down the inclined table, and su cient liquid is, in the operation of the machine, discharged from the receptacle Gto have at all times enough thereof on inclined table E to wholly immerse such apron and any sheet of glass which is on the apron over the inclined table.

H, H are tanks into one or both of which liquid from collectin pan F is discharged.

f is a steam supp y pipe branched at the lower end thereof to discharge into the tanks H, H, andf,f, are valves m pi efto control the discharge of steam there om. The liquid contents of tanks H, H, respectively are heated by discharging steam thereinto from such pipe f. I

h is a water su ly pipe arranged to discharge into tank I is a pipe one end whereof isT-shaped and spectively,

livered into receptacle G. This machine is, as heretofore stated, de-- signed to be used for the cleaning of glass requiring strong lye or other chemical compounds and have found that where lye is used rovision should be'made for prevention 0 foamin that is, to revent the formation of air bu bles; and or this purpose I,

provide the auxiliary receptacle having the foraminated bottom g (see Flg. 1) into which auxiliary receptacle and through the foraminated bottom thereof liquid from tank G flows onto the apron B and inclined table E adjacent to the upper end of such inclined table By means of the two tanks H, H, respectively provided with steam pipes 73.]; warmed ye, (as say in tank H) or warmed water, or water saturated with any desired chemical, (as say in tank H), may be used over and over in the cleanin'gof glass and 1 maintained at a determined temperature. I

prefer to construct the tanks H, H, of sufficient size so that not less than one .half a days run may be made before the cleaning liquid contained in either one of such tanks becomes so dirty as to require a fresh sup ly.

J, J, Figs. 1 and 2, are adjustable bIUS lIQS adjacent to the apron B, screws by means of which such brushes are adjusted. These brushes J, J, are so near to .the apron B that whenthe sheets of glass on such apron are carried thereunder such brushes are in contact therewith, but do not rest thereon with suflicient force to break the glass. i A v K is a roller the surface whereof is preferably felt or other like material, rotatabl mounted on frame A to come in contact with a sheet of glass on the upper surface of such sheet at the time the ass is about-to be de: hvered from-apron onto a ron'L. This roller K has two functions; st, to insure the forward movement and delivery of the sheet of lass onto apron L, and secondly, to

l of which prevent he ca g over of any con-slderable 'uantity of liquid in-ca'se brushes J, J, shoul leave such liquid on the glass. Apron L is constructed in substantially the same crossslats Z and the belts l .m, m,'res ectively.

O, O, are rollers one above the other below the plane in which the sheet of glass which is being transferred onto apron .L moves. These rollers move in the same direction; the periphery of roller 0 at the point where t movingin the same direction in which the sheet of glass is moving and the periphery of roller 0 at the oint thereof in contact with such sheet of g ass moving in the direction 0 posite to the movement of such sheet of g ass. I have madethe-roller O, O, with brushes on the periphe thereof; that is, such rollersform brush ro lers.

O, O, are the shafts of the respective brush rollers O, O, and are rotatably'mounted in frame A.

P, P, are, respectively, water tending transversely across the mac e from one side thereof to theother and provided with perforations directing the water from such ipes on to the u of a'sheet of glass whic is being transferred from apron B to apron L-before such sheet of glass is delivered to such apron L. Transverse pipe P is above and transverse pipe P is below the plane of the sheet of glass.

Q is a collecting pan under the apron L by means ofwhich thewater used to rinse the glass on apron L is c llected, and discharged, so far as this machin'e is concerned, to waste.

means of which R, R, are motors. Motor R actuates' aprons B and -L, respectively, and' roller brushes 0, '0'; by means of the several shafts S, S, S", intermeshing ears S S pulleys T, T, t, t, t, and belts U, U, U, U.

The operation of this machine is as'follows;A sheet of glass is laid onthe a ron at the lower end thereof with the side 0 the glass particularly to be cleaned u The apron slowly conveys the sheet of g ass forward and upward and when the forward edge of such sheet of lass comes over the inclined table the liquid owing downs'uch table will flow over the sheet of glass, on both the under '8,I1d

per and lower faces.

pulley rotary upper faces thereof. -Where the sheets of glass to be cleaned have previously ipes exbubble is used the su plemental pan with a foraminated bottom 1s used, and the liquid flowing thereinto from receptacle G flows out therefrom through the holes in such bottom.

As the aprontravels slowly the sheet of glass.

is subjected to the flow of cleaning liquid say from two to five minutes, as desired. As the sheet of glass asses under the brushes J, J, the cleaning liquid on the to surface is brushed therefrom and the g ass is then transferred to apron L, in the course of such transfer passing between the brush rollers O, O. The cleaning liquid falling from the inclined table under a ron B flows into the collecting pan F and rom thence into the one of the tanks H, H, which is in use. Such liquid is maintained at the determined temperature by injecting thereinto steam from pipe f, the valve f being opened sufficiently I to obtain and maintain the determined temperature in such cleaning li uid.

The transverse ipes P, are perforated so thatwhen no s ee-t' of glass is passing between the brush rollers many small jets of water are thrown towards such rollers and when a sheet of glass is assing between such brush rollers these small jets of Water are directed from above down onto the u per surface of such sheet of glass and from elow up onto the under surface thereof. The water thus thrown on to the sheet of glass from these jets is preferably cool, say about seventy degrees temperature, and I have used water direct from the city pressure pipes. The water from the glass drops into the collecting pan and flows to waste.

Having thus described my invention and i the o eration thereof what I claim is new and esire to secure by Letters Patent is, 1.
